In order to re-torque the heads you need to remove the rocker arms and the intake manifolds. Simply tightening them may help but since thre is a sealer used on the face you won't get the best results. Also due to the length of the studs some twisting will occur while tightening. A "clicker" torque wrench is not the best tool. Use either a beam or even better a dial indicator type wrench. 41 ft lbs. is the later spec. Keep in mind that if they are loose either they were not installed properly or the studs are stretching. If a stub breaks you are "down" so if this is your only vehicle be prepared for it going out of service. A broken stud will mean head and cylinder removal. If a stud breaks close to the case you are looking at a full teardown and a visit to a machine shop. If really close you may be looking for an engine. Done that twice.

Thanks Dennis!

Perhaps I should find another shop. I'm not sure where that number came from, but good to know it seems high. I'd rather do what work I can on it, aside from the cost, getting to/from the mechanic is not easy - especially if stranded on a trip.

To re-torque the heads, I presume that is as simple as to remove the valve covers and tighten? I can probably borrow a torque wrench - I presume that is how I'd check they were loose. http://www.benplace.com/head.htm recommends 55NM (book says 50NM - 37 ft lb)

This sounds like an easy first stop before diving deeper.

And thanks for the tips on the exhaust. The bolts didn't look too bad last summer, no doubt replacing the bolts will save me grief later on as well.
